I got into the Cell Phone thing around 2000 or so. After a few different phones, problems, deaths, and an auto mishap (phone/tire) I finally had stuck to Nokia. After many of their models, I'm still using the 6255i, which some of my co-workers think looks like a folding brick. Well... After seeing 4-5 of my coworkers returning their Razr's due to unexplainable and utter failures, and a few more having their new touch screen thingamajigs lock up, My 6255i is still going strong.

What do you use, and what have you had positive/negative experiences with?
